Rock, Paper, Spears

[Strangler Lewis]

Some possibilities:

1) Cavewall couldn't cover rock or be cut by spear. They would say it did, but the rock and spear would keep falling to the ground in pieces. This would lead to the invention of paper for the integrity of the game.

2) Cavewall would always win--blunting spear and chipping rock--but early man was too dumb to pick it every time.

At any rate, still well done. I especially liked the 50s science video/film strip voiceover.
